Boneham LT4016JQ Headless L Drill Bushing Liner

Product Description

The BONEHAM LT4016JQ is a headless L-style drill bushing liner designed to guide drill bits with precision in jig and fixture applications. It features a 3/8 inch inside diameter, a 5/8 inch body outside diameter, and a 1 inch overall liner length. Manufactured from alloy steel hardened to 60-65 HRC, this liner provides the wear resistance required for high-cycle drilling operations. Installation is accomplished via press fit, seating the liner securely into a jig plate or tooling fixture. Machinists, toolmakers, and precision fabricators work with this component during fixture setup and maintenance.

This liner is used in drill jig applications across metalworking, machining, and precision fabrication environments. It is typically installed in a jig plate to accept interchangeable slip-renewable or fixed bushings, serving as the permanent receiver in the tooling assembly. The headless L liner style is suited for installations where a flush or low-profile configuration is required at the fixture surface. Applications span both production machining and toolroom environments where consistent hole location and repeatability are critical.

Key Features

• 3/8 inch inside diameter for precise drill bit guidance
• 5/8 inch body outside diameter for standard jig plate fitment
• 1 inch overall liner length provides stable bushing support
• Alloy steel construction hardened to 60-65 HRC for extended wear life
• Press fit installation method ensures secure, non-rotating seating in the jig plate
• Headless L-style design allows flush or low-profile installation at the fixture surface

Compatibility

Designed as an OEM-style replacement or standard production liner for drill jig fixtures requiring a headless L-series bushing liner with a 3/8 inch inside diameter and press fit installation.

Installation Notes

Press fit installation requires an arbor press or similar tooling to seat the liner flush and square into the jig plate bore. The receiving bore in the fixture plate must be machined to the appropriate tolerance for the specified press fit to prevent liner movement or rotation during drilling. Power down and secure any associated machinery before servicing or replacing drill bushings in an active fixture. Installation and fixture tolerancing should comply with applicable tooling engineering standards for jig and fixture construction.
